“…Among more than 130 scorpion species described in Brazil 8 , at least 11 harm humans, specifi cally the species Tityus serrulatus Lutz & Mello, 1922), T. bahiensis (Perty, 1833), T. stigmurus (Thorell 1876) and T. obscurus (Lourenço, 2008), which are responsible for serious envenomation or death, particularly in children 9 . Other scorpion species in this country from the Tityus genera reported to cause mild reactions include T. costatus (Karsch 1879), T. brazilae (Lourenço & Eickstedt, 1984), T. fasciolatus (Pessoa, 1935), T. metuendus (Pocock, 1897), T. neglectus (Mello-Leitão, 1932), T. mattogrossensis (Borelli, 1901), T. adrianoi Lourenço 2003) 10 and T. pussilus 11 .…”

Introduction: Envenomation by scorpion stings is a major public health problem in numerous tropical countries because of its frequent incidence and potential severity. Approximately 1,900 species of scorpions are known in the world, and at least 130 of these have been described in Brazil. Methods: This work reports on 3 child deaths caused by Tityus stigmurus stings and characterizes epidemiological and clinical surveys on pediatric cases of scorpionism recorded in the Centro de Assistência Toxicológica de Pernambuco (Ceatox-PE). Results: Scorpion stings accounted for more than 60% of all cases recorded for venomous animals. The children were from 37 cities of the State of Pernambuco and accounted for 28.8% of the victims treated for scorpion stings, with the highest incidence in the metropolitan area of Recife. Stings occurred throughout the year and slightly increased during the rainy season. Independent of the elapsed time for a prognosis, most cases showed mild symptoms. Three moderate cases that resulted in death featured cardiogenic shock and/or pulmonary edema or severe neurological symptoms. For the fi rst time, death attributed to T. stigmurus was confi rmed by the presence of the scorpion. Conclusions: These results suggest that scorpionism in Pernambuco is a public health problem that needs to be monitored carefully throughout the year by the government.

“…T. tayrona (misidentified as T. parvulus), which belongs to the subgenus Archeotityus, has been wrongly classified as dangerous (19), as members of this scorpion group are regarded elsewhere to be of little medical importance (70). Recently, a 5-yearold girl died after being stung by T. festae in the region of Chepo, El Llano-Cartí, west of the province of Panama (Dr. L. Coronado, personal communication, 10/11/2010), and a 6-year-old boy died after being envenomed by T. cerroazul at Quebrada Amarilla, La Mesa del Valle de Antón, province of Coclé (28).…”

Scorpionism in the Americas occurs mainly in Mexico, northern South America and southeast Brazil. This article reviews the local scorpion fauna, available health statistics, and the literature to assess scorpionism in Central America. Notwithstanding its high toxicity in Mexico, most scorpion sting cases in Guatemala, Belize, El Salvador, Nicaragua, and Costa Rica are produced by species in the genus Centruroides that are only mildly toxic to humans despite the existence of ion channel-active toxins in their venoms. Regional morbidity is low with the exception of Panama, where an incidence of 52 cases per 100,000 inhabitants was recorded for 2007, with 28 deaths from 1998 to 2006. Taxa belonging to the genus Tityus (also present in the Atlantic coast of Costa Rica) are responsible for fatalities in Panama, with Tityus pachyurus being the most important species medically. Most Tityus species inhabiting Panama are also found in northern South America from which they probably migrated upon closure of the Panamanian isthmus in the Miocene era. Incorporation of Panama as part of the northern South American endemic area of scorpionism is thereby suggested based on the incidence of these accidents and the geographical distribution of Panamanian Tityus species.

“…The endemic Brazilian Cerrado scorpion Tityus (Archaeotityus) mattogrossensis (Borelli, 1901) is found in the Brazil Midwest, Bahia and north of Minas Gerais states [ 8 ] . Tityus (Archaeotityus) mattogrossensis sting is considered of small severity due to the low degree of reaction and the few recorded cases [ 9 ]. The accident with species of the subgenus Archaeotityus is considered mild and moderate, commonly presenting pain at the sting site shortly after the accident and paresthesia in the affected area.…”

Background: Almost all Tityus characterized toxins are from subgenera Atreus and Tityus , there are only a few data about toxins produced by Archaeotityus , an ancient group in Tityus genus. Methods: Tityus (Archaeotityus) mattogrossensis crude venom was fractionated by high performance liquid chromatography, the major fractions were tested in a frog sciatic nerve single sucrose-gap technique. Two fractions (Tm1 and Tm2) were isolated, partially sequenced by MALDI-TOF/MS and electrophysiological assayed on HEK293 Nav 1.3, HEK293 Nav 1.6, DUM and DRG cells. Results: The sucrose-gap technique showed neurotoxicity in four fractions. One fraction caused a delay of action potential repolarization and other three caused a reduction in amplitude. An electrophysiological assay showed that Tm1 is active on HEK293 Nav 1.3, HEK293 Nav 1.6, DUM and DRG cells, and Tm2 on HEK293 Nav 1.3 and DRG cells, but not in HEK293 Nav 1.6. In addition, Tm1 and Tm2 did promote a shift to more negative potentials strongly suggesting that both are α-NaScTx. Conclusion: Although Tityus (Archaeotityus) mattogrossensis is considered an ancient group in Tityus genus, the primary structure of Tm1 and Tm2 is more related to Tityus subgenus. The patch clamp electrophysiological tests suggest that Tm1 and Tm2 are NaScTx, and also promoted no shift to more negative potentials, strongly suggesting that both are α-NaScTx. This paper aimed to explore and characterize for the first time toxins from the ancient scorpion Tityus (Archaeotityus) mattogrossensis.
